The self-righteous children on social media dismiss any observation of reality as bigotry. It's not bigotry. It's human nature. We develop customs and habits over generations, comfort and continuity are important. If you change things overnight, societies fracture, populations tend to explode. We've seen that happen. The industrial revolution produced an arms race! We got Hitler and Stalin, hundreds of millions died. Yes we did get antibiotics in the end, but we also got genocide. There's a lesson in that. If you're changing things, go slowly. Change should be incremental. Explain yourself and reassure people as you do it. Acknowledge the reality of evolutionary biology. Human beings are not born to be machine components, you can't improve them like on. Even open-minded ones get jumpy when everything's different. Wise leaders would know that intuitively. If you're going to have relentless technological change, and we are, you cannot inflict relentless social change. Things will fall apart. That's what our leaders are doing, they're changing everything. A new language, a new biology, new curricula, new social mores, and body types? A brand new national population.
